Indicator generated by accessibility model based upon a GIS flight network dataset, a GIS NUTS-3 region layer and NUTS-3 region population figures.
The indicator is available in ESPON for three distinct years, 2001, 2006 and 2011 for entire ESPON space. Neighbouring countries are, however, not yet included.
Although the flight networks change every half year, for reasons of comparability with the other accessibility potential indicators a 5-year update interval for this indicator is justified.
Data available at NUTS-3 level and higher.
